Summary: Incorporating standard model Yukawa interactions into a grand unified theory often leads to the prediction of new scalars that couple to fermions, resulting in novel observational effects. In this study, we investigate the possibility of color sextet diquark scalars within realistic renormalizable models based on SO(10) GUT. We find that, in the realm of realistic models, the observed neutron-antineutron oscillation cannot be observed in near future experiments.

Summary: The proposed work extends the Standard Model by introducing two gauge symmetries to study neutrino phenomenology, lepton flavor violation, and leptogenesis. The model is able to predict neutrino oscillation results in accordance with experimental data, explain electron and muon (g - 2) results, and account for matter-antimatter asymmetry in the Universe. Furthermore, the model can be tested in upcoming long-baseline experiments.

Summary: The HIBEAM/NNBAR program aims to search for baryon number violation by converting or oscillating neutrons into sterile neutrons and/or antineutrons at the European Spallation Source. An annihilation detector is being constructed to directly observe the production of an antineutron following the oscillation. Geant4 simulations are used to study the predicted response of the detector models, with focus on particle identification and discriminating observables like invariant mass and sphericity.

Summary: This study investigates the flutter performances of a streamlined bridge deck sectional model using a newly developed testing device, analyzing the flutter behaviors at different initial angles of attack, hysteresis phenomena, and energy budget properties. Experimental results show divergent vibrations and limit cycle oscillations for various initial angles of attack, with observations of hysteresis behavior and the influence of initial impulse excitation on vibration amplitudes and critical flutter velocities. Additionally, the vertical-to-torsional amplitude ratio and energy dissipation dynamics are discussed.

Summary: This study investigates the post-flutter bifurcation behavior of a twin-box bridge deck and finds that the aerodynamic nonlinearities significantly affect the stability of the bridge deck. A novel wind-tunnel technique is used to measure the aerodynamic force during post-flutter oscillations, and a corresponding nonlinear model is proposed to describe the observed behavior.

Summary: A specialized testing device was used to study the nonlinear post-flutter behaviors of a typical steel-truss girder bridge deck under large torsional amplitude vibrations. The results showed significant vertical-torsional coupled soft flutter behavior at various attack angles, with stable and unstable limit cycle oscillations observed near the critical speed. Additionally, various factors such as added aerodynamic damping, coupling vertical deformation, and wind-induced aerodynamic damping exhibited amplitude dependence characteristics.

Summary: The present study investigates the post-critical behavior of a side-box steel-concrete composite girder under varying wind angles of attack through section model testing. It reveals the essence of flutter and the adverse impact of vortex shedding lock-in on exacerbating post-critical flutter responses. The results indicate that the flutter motion of the prototype composite girder can be characterized as a supercritical Hopf bifurcation with phase shifting between motions.

Summary: This study investigates emergency decision-making behaviors in uncertain time limits and life loss scenarios. The results show that prior experience influences the estimation and consumption of time for comparing rescue options in future disasters. In addition, the study reveals a risk shift, where risk-averse individuals without time limits exhibit risk-taking behaviors when time constraints are introduced. It is also found that as time pressure increases, subjects are more likely to use heuristics and adopt specific decision strategies. The findings suggest that emergency managers should be aware of the anchoring effect of prior experience and the potential risks associated with seeking to save more people.

Summary: This study investigates the dynamical mechanism by which the quasi-biennial oscillation (QBO) impacts the temperature anomaly in the equatorial upper troposphere and lower stratosphere (UTLS) associated with the Madden-Julian oscillation (MJO). The results suggest that the QBO modulates the wave energy dispersion, playing a major role in determining the localized UTLS temperature anomaly. The observed temperature response becomes colder and more in phase with the convection during the easterly QBO phase, while the opposite is observed during the westerly QBO phase.

Summary: This study presents an efficient and robust adaptive remeshing strategy in kinematic upper-bound limit analysis using six-node triangular elements and Second-Order Cone Programming. The proposed method, UBFEM-SMRC, demonstrates more rigorous solutions and significantly reduces computational burdens compared to the Pure Mesh Refinement scheme. The synchronous adaptive mesh refining-coarsening process results in clearer adaptively refined mesh zones with intensive plastic dissipations, which can accurately reproduce potential failure mechanisms of geotechnical problems.

Summary: Neutron star mergers provide a novel environment for studying new physics beyond the Standard Model. In this study, we considered a simple extension of the scalar sector involving a light CP-even scalar singlet S that mixes with the SM Higgs boson. We found that S particles can be produced abundantly in neutron star mergers and may either be trapped or stream freely out of the merger remnant. Our results show that the S particles can act as an extra cooling channel in the free-streaming region and contribute to faster thermal equilibration in the trapped region. Therefore, future observations of neutron star mergers could effectively probe a unique range of the S parameter space.

Summary: High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles beyond the acceptance of existing experiments. The proposed Forward Physics Facility (FPF) will host experiments to probe standard model processes and search for physics beyond the standard model (BSM). FPF experiments will explore BSM physics through searches for new particle scattering or decay signatures and deviations from SM expectations in a low-background environment.

Summary: We propose a low-scale type-I seesaw scenario with discrete flavor and CP symmetries that not only explains the measured values of lepton mixing angles but also predicts leptonic CP violation and connects low-energy CP phases with high-energy CP phases. The scenario involves three quasi-degenerate right-handed Majorana neutrinos whose decays can explain the observed baryon asymmetry through resonant leptogenesis. The study explores the correlation between the predicted baryon asymmetry and lepton-number-violating signals at high-energy colliders and low-energy neutrinoless double beta decay experiments.

Summary: The article discusses a hidden U(1) gauge symmetry where only the right-handed neutrinos (vR) are charged. The corresponding gauge boson, called the vR-philic Z', can be experimentally accessible through loop-induced couplings via left-right neutrino mixing. The vR-philic Z' has stronger couplings to neutrinos than to charged leptons and quarks, making it an interesting scenario for future neutrino experiments.

Summary: The longstanding muon (g - 2) anomaly and hints of lepton flavor universality violation in B-meson decays may indicate new physics beyond the Standard Model (SM). The RPV3 framework, which involves light third-generation sfermions, presents a compelling solution to these flavor anomalies and other issues in the SM. We propose a new RPV3 scenario to explain the muon (g - 2) anomaly and suggest strategies to improve the current constraints using LHC data.

Summary: We explore the parameter space of lepton flavor violating neutral Higgs Yukawa couplings and study the LFV prospects of a generic beyond the Standard Model neutral Higgs boson with a mass range of [20; 800] GeV at the high-luminosity Large Hadron Collider (HL-LHC) using the vector boson fusion (VBF) Higgs production process. We compare our projected sensitivities for the Standard Model Higgs LFV branching ratio with current and future low-energy constraints, and also provide model-independent upper limits on the VBF production cross section of the neutral Higgs boson times its branching ratio in the H-mu tau channel at the HL-LHC.

Summary: In this study, we consider the interaction between dark matter and Standard Model leptons. We analyze the potential of future lepton colliders to detect such leptophilic dark matter in the mono-photon and mono-Z channels. Using an effective field theory framework, we consider all possible dimension-six operators and determine the collider sensitivities as a function of dark matter mass. Our results show that the International Linear Collider can probe leptophilic dark matter at a high sensitivity level in the low-mass regime.

Summary: We study the phenomenology of leptophilic Z ' gauge bosons at future high-energy e(+)e(-) and mu(+)mu(-) colliders, as well as at gravitational wave observatories. We find that future e(+)e(-) and mu(+)mu(-) colliders with multi-TeV center-of-mass energies provide unprecedented sensitivity to heavy leptophilic Z ' bosons. Moreover, if these U(1) models are classically scale-invariant, the phase transition at the U(1) symmetry-breaking scale tends to be strongly first-order with ultra-supercooling, and leads to observable stochastic gravitational wave signatures. We also find that the future sensitivity of gravitational wave observatories can probe higher Z ' masses, complementing the collider experiments.

Summary: The recent results from the Fermilab muon g-2 experiment and the hints of lepton flavor universality violation in B-meson decays provide strong evidence for new physics beyond the Standard Model. We propose a minimal R-parity violating supersymmetric scenario with light third-generation sfermions (RPV3) as a natural and well-motivated framework to explain all flavor anomalies. This scenario is consistent with both low-energy flavor constraints and high-energy collider searches. We also suggest specific collider signatures for the sbottom and sneutrino particles in this scenario.

Summary: Particle physics is at a crossroads, as the completion of the Standard Model and the observation of anomalies beyond the model offer both opportunities and challenges for future research. Systemic deficiencies in experiments and search strategies may hinder the discovery of beyond the Standard Model physics, but new search strategies utilizing CERN open data can help uncover hidden signatures. Access to open data is crucial for fully exploiting the potential of the Large Hadron Collider (LHC).

Summary: This article discusses the minimal U(1)(X) extension of the Standard Model, where the coupling of the new neutral gauge boson (Z') with the SM fermions is determined by the U(1)(X) charges of the new scalar fields. The study finds that future e(-)e(+) colliders can be used to probe multi-TeV Z' bosons through observables such as angular distributions, forward-backward (AFB), left-right (ALB), and left-right forward-backward (ALR-FB) asymmetries.

Summary: The P2 experiment aims to study leptoquarks through high-precision measurements of the parity-violating asymmetry in electron-proton and electron-C-12 scatterings. The experiment is sensitive to operators in the Standard Model effective field theory and leptoquark parameters, and can test energy scales up to 15 TeV. Additionally, the experiment can resolve degeneracies of different operators and address potential tensions between theoretical and experimental determinations of the weak charge of Cs-133.
